 Neither gcc or clang support "-march=generic". But since
 https://git.ffmpeg.org/gitweb/ffmpeg.git/commit/abc346de735cae1b9316b7b853aa2d2661ab40fb
 it can be used by the configure script.

 Since the LTO linker flag is checked together with $cpuflags
 (https://git.ffmpeg.org/gitweb/ffmpeg.git/blob/e758b24396a427598ebb13e1589f6aeccdae0466:/configure#l7511),
 this results in the LTO linker flag not being used when linking the shared
 libraries which, in some cases, results in a build error.
